How to Prepare Your DFW Home for Freezing Temperatures

North Texas doesn't get much winter, and that's exactly the problem. Homes here are built for August, not January — supply lines run through unconditioned attics, slabs sit close to grade, and a house that shrugs off 105 degrees can lose a ceiling to eighteen hours below freezing.

The standard winterizing checklist is easy to find and worth doing. What's harder to find, and what actually determines whether a freeze costs you a weekend or thirty thousand dollars, is how your insurance policy reads and what the damage does to your house years later when you sell.

What actually fails in a North Texas freeze

Three vulnerabilities account for most of the damage here, and none are the ones people worry about.

What your insurance will and won't pay for

This is the part almost no winterizing article covers, and it's the one worth reading twice.

A standard homeowners policy excludes loss caused by freezing of a plumbing, heating, or air conditioning system. But the exclusion comes with an exception written directly into the form: it doesn't apply if you used reasonable care to maintain heat in the building, or shut off the water supply and drained the system.

Read that as a rule about behavior, not equipment. Two people can suffer identical burst pipes and get opposite claim outcomes. The one who kept the thermostat up is covered. The one who left for the holidays, turned the heat off to save money, and left the water on may not be.

If you travel during winter, you have two defensible choices: leave the heat on at a reasonable setting, or shut the water off at the main and drain the lines. Doing neither is the expensive option.

The second thing worth knowing: a policy generally pays for the water damage the break caused — the ceiling, the flooring, the contents — but typically not the repair or replacement of the pipe that failed. That surprises people at the worst possible moment.

There's a scenario that connects the two halves of this, and North Texas learned it the hard way in February 2021: what happens when the power goes out and you can't maintain heat?

You can't control the grid, but you can control the other branch of that exception. If an extended outage arrives during a hard freeze and the house is dropping toward freezing, shutting off the water at the main and opening the faucets to drain the lines is both the practical move and the one that keeps you inside the policy language. Know where your main shutoff is now — in the yard near the street in most North Texas homes, usually needing a meter key — rather than looking for it by flashlight at 2 a.m. A fifteen-dollar meter key in the garage is cheap insurance against a ceiling.

The rest of the outage checklist still applies: flashlights and batteries rather than candles, water stored before the storm, phones and power banks charged, a full tank of gas, and blankets in the car if you have to be on the road. Space heaters stay at least three feet from anything flammable and never run unattended.

Policies differ, and yours is the one that governs. Pull it out before the first freeze warning, read the freezing language, and call your agent about anything ambiguous. The Texas Department of Insurance publishes consumer guidance on homeowners coverage and the claims process, and it's written for people rather than adjusters.

What a freeze costs you at resale

Here's the part I see as a REALTOR® that homeowners rarely think about in February.

A freeze repair doesn't end when the drywall is patched. Under Texas Property Code § 5.008, the Seller's Disclosure Notice asks what you know about the condition of the property — including water penetration and previous repairs — completed to the best of your knowledge.

Worth being precise here, because this gets misstated: the form's flood questions are about natural flood events and reservoir releases. A burst pipe is not a flood, and it doesn't make you answer yes to those. But the repair itself is something you know about, a buyer will ask, and an inspector will often find — fresh drywall in one ceiling bay, a section of replaced supply line, a water stain that was painted over.

The sellers who have trouble are not the ones who had freeze damage. They're the ones who can't document the repair. Keep the plumber's invoice, the remediation report, and any moisture readings. A documented, properly repaired break is a non-event in negotiation. An undocumented one becomes a price reduction, because the buyer has to assume the worst.

Two adjacent things are worth understanding before you sell: what the Texas Seller's Disclosure Notice actually requires, and how repair negotiations work after an inspection — because that's where undocumented past damage costs real money. If a freeze also moved your slab, foundation issues in North Texas covers how our soils behave and what buyers and their lenders expect to see.
